Why Choose the ABB S201M-Z1UC Miniature Circuit Breaker?
The ABB S201M-Z1UC, order code 2CDS271061R0218, is a high-performance single-pole miniature circuit breaker (MCB) for AC and DC applications. Part of the ABB System pro M compact® S 200 M UC series, it provides reliable overload and short-circuit protection for sensitive industrial, control and direct-current circuits.
Rated at 1 A with a Type Z tripping characteristic, the S201M-Z1UC provides sensitive magnetic protection suited to circuits where rapid response to relatively low fault-current multiples is required. Its universal-current construction enables operation in both AC and DC installations, including applications at 230 V AC and up to 220 V DC with a single pole.
The S201M-Z1UC provides an ultimate short-circuit breaking capacity of 10 kA at 230 V AC and 10 kA at 220 V DC, rising to 20 kA at 110 V DC. Its compact DIN-rail construction and compatibility with ABB System pro M compact® accessories make it a flexible protection solution for automation, instrumentation and industrial DC systems.

Sensitive Universal-Current Circuit Protection
The ABB S201M-Z1UC combines thermal overload protection with a sensitive magnetic short-circuit release. Its Type Z characteristic makes it particularly useful for protecting sensitive equipment and long cable circuits where rapid interruption at relatively low fault-current multiples is important, including suitable TN and IT system applications.
The S 200 M UC range is engineered for universal-current operation and supports both AC and DC installations. ABB specifies the single-pole configuration for DC applications up to 220 V DC, while two-, three- and four-pole arrangements within the wider series can be used for DC voltages up to 440 V DC. Correct polarity must be observed in DC installations.
Typical Applications
- Industrial low-current control circuits.
- Sensitive electronic and instrumentation circuits.
- AC and DC electrical distribution panels.
- Automation and machine control systems.
- Long cable circuits in TN and IT systems.
- DC auxiliary and battery-powered systems.
- Railway and transportation electrical equipment.
- OEM machinery and industrial control-panel construction.
